Yeah, they are called Trappist Breweries. I think there are only 7 in the world and they make amazing beer.

From wiki:

A Trappist beer is a beer brewed by or under control of Trappist monks. Of the world's 171 Trappist monasteries (as of April 2005), seven produce beer (six in Belgium and one in The Netherlands). Only these seven breweries are authorized to label their beers with the Authentic Trappist Product logo that indicates a compliance to various rules edicted by the International Trappist Association (see details below).

awesome, did not know that. I wonder if there are other, non-trappist monks that brew beer, cuz I'm pretty sure I've had like French and Austrian beer that was monk-brewed ha, but I could be wrong. Or maybe it's one of those deals where the beer started in a monastery then moved out but they still use the monastery name to sort of keep it classy.
